Specification of Letters Patent.

To all whom, it may concern.-

Be it known that I, AGNES S. ADAM, a citizen of the United States, residing at Wash ington, in the District of Columbia, have invented certain new and useful Improvements in Pea-Shelling Machines, of which the following is a specification.

My invention relates to an improvement in pea shelling machines and the object is to provide a simple mechanism capable of being is a view in perspective of my improved ma' chine. Fig. 2 is a plan view. Fig. 3 is a longitudinal, vertical section. Fig. 4 is a transverse vertical section. Fig. 5 is a rear view, Fig. 6 is a perspective View of the cap plate and fingers, Fig. 7 is a side view of one of the extension plates, and Fig. 8 is a view in perspective of one of the side plates.

A, represents a portion of the frame which forms a housing for the rubber facing rolls 1 and 2, and the journals 3, 3, and 4, 4, respectively, and these rolls turn in bearings 5, 5, and 6, 6, respectively, formed in the side plates 7, 7, which latter are removably secured to the sides of the frame A, by screws or other means 8, 8, The upper bearings 5, 5, are preferably elongated vertically as indicated to permit the journals to move up and down therein, and the purpose of this construction is to permit one of the rolls, namely the upper roll to yield to irregularities in size of pods being shelled, and also to permit the adjustment of the upper rolls to cause it to act with greater or less pressure upon the pods passing between the rolls and being shelled. This adjustment is effected in a very simple manner and is as follows. The pins 9, 9, fit loosely in holes 10, 10, and wh1le the inner ends of these ins bear upon the journals of the upper rol er, their outer ends protrude more or less beyond the top plate of the frame A spring plate 11 spans the distance between these two pins and the pins are secured to its outer ends. A supplementary spring 12, is preferably placed upon the spring spanning plate and a thumb screw 13 extends through holes 14 and 15 in these two plates and its threads turn into a threaded hole 16 in the top of the frame so that by turning this thumb screw to the right the pressure upon the pins and hence the journals of the upper roll is increased equally at each end and the pressure is diminished by reversing the thumb screw and turning it in the opposite direction. Also by this means the roll is permitted to yield bodily or at either end.

The rolls are turned by'means of a hand crank 17 or a pulley on one end of the shaft of the lower roll. On the opposite end of this shaft a gear wheel 18 is secured and the teeth of this wheel intermesh with the teeth of a wheel 19 on the shaft of the upper roll, whereby motion is communicated from one roll to another. Back of the wheel 19 a larger gear wheel 20 is secured and the teeth of this wheel engage the teeth of a large gear 21 on the end of the shaft of a roller 22 which carries the endless feed belt 23 which carries the peas or beans to the shelling rolls, the outer end of the endless belt passing around the roller 22. The journals of these rollers 22 and 22 are held in bearings 24, 24, in theremovable extension plates 25, 25, screws 26, 26, or similar devices being-employed for securing them to the flanges 27, 27 projecting rearwardly from the frame A. The peas are valined in their forward movement by fingers 28, 28, on the cap plate 29, and this cap plate is held down by means of embracing lugs which engage the upper edges of the extension plates.

The hopper 30 is removably secured to the side plates, it being conveniently provided with a depending flange 31 at the rear end which has holes adapted to receive studs 33, 33, projecting rearwardly from the rear ends of the extension plates and the forward end of the hopper is provided with embracing flanges 34, 34, which overlap the extension plates and these flanges and extension plates are provided with holes 35, 35 and 36, 36, adapted to receive screws 37, 37 which are threaded therein. In this way the hopper which is preferably made in a single casting not only serves the primary purpose of holding the peas or beans and feeding them upon the endless belt to the shelling rolls, but also when thus constructed it serves the secondary function of holding the extension plates in place and prevents their spreading as well as retaining the cap plate with its fingers in place. The two spouts 38 and 39, remov- ITO ably secured in place by screws 40, and 41, conduct the peas or beans in one direction and the pods in another. A clamp 42 with a clamp screw 43 is provided as a convenient means for securing the shelling machine to a table or bench.

In the larger size machines, used for hotels, it is designed to employ a set of agitators to mechanically assist in alining the pods so that they will move forward endwise. These agitators 48, 48, are preferably hinged as at 49, 49, to the hopper and they extend within approximately the full length of the hopper wherein they are made to slowly vibrate up and down. At their outer ends they are provided with the crank arms 50, 50, and from the outer ends of these crank arms, rods 51, 51, extend to wrist pins 52, 52-, on a gear wheel and crank such as 19 and 19 on opposite ends of the shaft of the upper shell ing roll. These crank pins are located on opposite sides of the axle so that the agitators are vibrated alternately or oppositely, one upward while the other is vibrating downwardly. In this way the peas or beans are stirred and lifted so that they become properly lined in the funnel that extends cross-wise of the hopper. A short space 53 intervenes between the traveling belt and the shelling rolls and through this opening the peas or beans dro as they are shelled out of their pods, an a spout 39 beneath this opening conducts them to a suitable receptacle, While the pods continue on through rolls into the spout provided for them.

As previously stated the machine may be operated by hand or power accordingly as found most convenient. It will be seen that the machine comprises few and simple parts all of which are easily removed and taken apart for the purpose of cleaning the machine so that it can be kept perfectly clean and sanitary.

It is evident that slight additional changes might be made in the form and arrangement of the several parts described, without departing from the spirit and scope of my invention, and hence I do not wish to limit myself to the exact construction herein set forth, but

Having fully described my invention, what I claim as new and desire to secure by Letters Patent, is

1. The combination of frame A, side plates connected thereto, and carrying the shelling rolls, extension plates secured at one end to the side plates, a cap plate bridging the extension plates, and carrying guide fingers, and a hopper mounted on and secured to said extension plates, and holding the cap plate and guides in position.

2. In a pea shelling machine, the combination with a frame, shelling rolls supported thereby, a hopper and an endless feed belt in the bottom of the hopper, of shafts journaled at one end of the hopper, agitators secured to the shafts, and extending into the hopper, crank arms extending from the shafts, gearing for giving motion to the rolls and connecting rods through which the shaft of one of said rolls gives motion to said crank arms to operate said agitators.

3. In a pea shelling machine, the combination with a frame, shelling rolls su ported thereby, a hopper, an endless feed be t in the bottom of the hopper, and means for insuring the endwise feed of the unshelled peas to the rolls, of shafts journaled at one end of the hopper, agitators secured to the shafts, and extending into the hopper, crank arms extending from the shafts, gearing for giving motion to the rolls and connecting rods through which the shaft of one of said rolls gives motion to said crank arms to operate said agitators.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
